| 摘要 |
The invention is a system for the mass production of paper shoppers or bags (B)5 comprising a station (2) for feeding at least one continuous paper strip (N) along a longitudinal advance direction (L), and at least one station (3) where the continuous strip (N) is folded along a longitudinal folding line (L'). The folding along the latter line is carried out in such a way that at least one pair of longitudinal laps (S', S") substantially face each other, wherein said longitudinal laps (S', S") define corresponding opposite sides (P', P") of the bags (B). In particular, the folding station (3) comprises guide means (6) for the strip (N) that are suited to move both the longitudinal laps (S', S") from a substantially horizontal position to a substantially opposite vertical position, thus forming the continuous bottom of the bag. |
